Grapevine ‘Sheegene-12’

ABSTRACT

The new and distinct variety characterized by a dark red-colored, medium sized seedless grape that ripens in early August approximately two weeks later than the Flame Seedless Grape (unpatented) when grown in the San Joaquin Valley of Central California. The grapes of this variety are produced on strong woody stem and branches and are well adapted to commercial handling.

Latin name of the genius and species of the plant claimed: The claimed plant relates to a new and distinct variety of Vitis vinifera to be known as ‘Sheegene-12’.

Variety denomination: This invention relates to a new discovery and asexual reproduction of a new variety of Vitis vinifera. The new variety was first hybridized by Timothy P. Sheehan of Porterville, Calif. in late Spring 2000; first flowering occurred in May 2003. The pollen parent is Princess (unpatented) and the seed parent is Red Globe (U.S. Plant Pat. No. 4,787). The new variety was asexually propagated in the dormant season of 2003/2004, bud grafted on Harmony, virus-free rootstock, in a Vitis vinifera variety block located near Fowler, Calif. on the west side of Thompson Road, north of Adams Road. The dark red-colored seedless grapes produced by the new variety are medium in size and mature approximately two weeks later then Flame Seedless (unpatented). The new variety has been shown to maintain its distinguishing characteristics through asexual propagation.

The new variety is distinguished from its pollen parent, Princess (unpatented), in that the new variety produces dark red-colored seedless grapes, as compared to the white-colored grapes produced by the pollen parent, Princess (unpatented). The new variety is distinguished from its seed parent, Red Globe (U.S. Plant Pat. No. 4,787), in that the new variety produces seedless grapes, as compared to its seed parent Red Globe (U.S. Plant Pat. No. 4,787), that produces seeded grapes.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of grape which will hereinafter be denominated as ‘Sheegene-12’ and more particularly as a grapevine which produces a dark red-colored seedless table grape that matures in early August in the San Joaquin Valley of Central California. The new invention most closely resembles Flame Seedless (unpatented) but it produces a dark red-colored medium size grape that is sweet, has very good flavor, and matures at least two weeks later.

SUMMARY OF THE INVENTION

The ‘Sheegene-12’ grapevine is characterized by producing a medium sized, dark red-colored seedless grape with very good flavor that is mature for harvesting and shipment in early August in the San Joaquin Valley of Central California. The new variety can be compared to Flame Seedless (unpatented) but the grapes mature at least two weeks later, among other distinguishing characteristics.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing is a colored photograph of the grapes produced by the subject variety; several leaves are displayed as well as a typical section of the vine. Across the top of the color photograph on each side are secondary growth clusters; and in the center is a shoot with leaves and tendrils. Across the middle of the color photograph on the left is a mature grape cluster; and to the right is a mature leaf displaying the bottom surface and petiole. Below the mature grape cluster are four grapes cut in half longitudinally as well as horizontally displaying the flesh and shape. Across the bottom of the color photograph to the left is a mature leaf displaying the topside of leaf and petioles; and to the right is a mature cane displaying tendrils, nodes, and small leaves.

1. A new variety of grapevine to be known as ‘Sheegene-12’, substantially as illustrated and described, characterized principally by its production of dark red-colored, medium sized seedless grapes, that mature approximately two weeks later in the season of ripening than does the Flame Seedless Grape (unpatented) which it closely resembles.
